SHUTTLE. i

Application filed June 3, 1925.

This invention relates to means for securing wound packages on the spindles in shuttles. One object is to provide a securing means which is especially adapted for securing on such spindles the paper cops or tubes which are frequently used to form'the cores of the packages. Another object is to construct means for securing wound pack-A ages on shuttle spindles so that the loaded spindle will be firmly supported against lateral distortion or displacement in the shuttle.

In the drawing, l

Fig. 1 is a plan of a shuttle embodying the invention in the preferred form;

Fig. 2 is a fragmentary plan partly in section, showing a paper cop in secured position and partly in section;

Fig. 3 is a side elevation, with the rear wall of the shuttle broken away; and

Fig. 4 is a fragmentary plan of a shuttle embodying a modifiedv form of the invention.

In the drawing, l designates the shuttle body having the usual cavity 2 for the filling package formed with extension 3, or

portion of reduced width, at one end thereof. 4 is the spindle, of usual construction (except Yas hereafter noted). pivoted at its butt to move in a vertical plan on a pin 5 which traverses the cavity extension 3; 6 is' the spindle. spring which bears against they spindle butt and obtains the necessary support in order to be tensioned on the pins 7, also traversing the cavity extension.

In Figs. 1 to 3 are shown two claw members 8. These are arranged in the cavity eX- tension 3 one on each side of the spindlebutt and penetrated by pin 5, and their lateral faces 8a are flat so as to bear sduarelv against the lateral flat surfaces of the spindle-butt and sides of said cavity-extension, between which they snugly fit. Each claw member has its claw proper 8b proiecting toward the other and this, the acting` portion of each claw, has a bearing at 8C against the side of the cavity 3; in short. the clawproper of each claw member is in this example rigidly supported by the side of the shuttle against lateral displacement. The claw members are formed of somemetal, preferably aluminum.

The spindle et when depressed extends between the points of the two claws-proper, and in the best form of the invention it is Serial No. 34,552.

pressed into the recesses 4ta; in short, tliev spacingof the points of the claws-proper is less than the diameter of the tube. Thus the tube will be locked on the spindle, and the lock .will furthermore be substantially positive if, as explained, the material of the tube is held by the claws-proper pressed into the,

recesses 4a, each side of each recess as seen in Fig. 2 affording in effect a shoulder or abutment around which the material of the core is by the claw-proper held bent or deformed and so engaged with said abutment. There is the further important advantage, especially where the claws are rigid, as b being rigidly supported against lateral displacement by the sides of the shuttle body, that the loaded spindle is firmly reinforced against lateral distortion, as in the handling incident to applying thereto and removing therefrom thercop tube, and is also held in its properposition centrally in the shuttle notwithstanding any weer which may occur at the sidesof its butt or the sides of the cavity extension. It will beunderstood that when the spindle is swung up on its pivot 5 the tube is clear of the claws, so that it may be freelyv slipped on or removed from the spindle.

In Figa, the construction is substantially the same as that shown in the first three figures excepting that the claws-proper in this case are unsupported by, the sides of the shuttle body and areformed of metal (as steel) blades. These blades 9 forming the claws have flat portions 9a which are fitted snugly between the fiat sides of the spindleJ butt and the adjoining sides of the cavity extension, being penetrated by the pin 5, and claws-proper 9b which are formed by bending the relatively inner ends of the blades first outwardly and then inwardly toward each other. The extremities of the clawsproper are, as before, sufficiently close together so that when the spindle with the cop tube thereon is fully depressed said extremities are caused to press into the material of the tube, forcing it because .of its yielding nature into the recesses 4a. In this 'case it depends on the stiffness of the material of the claws both ,to secure the grip .on the tube and support the spindle -against lateral distortion or displacement.

I am aware that it is common in this art to employ claws or jaws on each side of the spindle having acting ends `projecting toward each other and arranged to engage in Ia circumferential `groove at the butt of the core, as the wooden quill of a wound package ,placed 'in the shuttle; but so far as I lknow it is new to construct the jaws or claws so vthat Atheir said acting vends will be Aspaced less than Athe 4diameter of the llingpackage corre, whereby when the core is placed on the spindle and the spindle 1s then depressed into lthe cavity the claws must bite into or indent :the core in order Ato accomplish -the full depressing or housing of thespindle. Preferably, as indicated, the yspindle has ka recess 4; `opposite the eX- tremity vof each claw-proper so "that the yielding material yof the core is forced into such .recess and `,a lock, substantially positive. in character, is i:formed between the core and spindle.

Having thus yfull-y described my invention what I claim anddesre-to secure 'by Letters Patent is:

l. In combination a-shuttle body 'having a filling-package cavity, a spindle having its `butt fulcrumed in theicavity'on anaxis vtraversing ithe same, a tubular filling-package core of yielding material on the spindle, ythe spindle havin-g laterally thereof in respect to its plane Yof inovability fan abutment facing lengthwise of the spindle, and a claw arranged lateral'ly'of said plane andbetween one sidefoffthe -spindle butt land the adjoining side of fthe cavity and having a clawproper projecting toward @the spindle and holding the 'material of Vthecore engaged with said abutment. l

2. In combination, ashuttle body having a filling-package cavity, a spindle having its butt fulcrumed fin the cavity on an axis traversing the same, a tubular .filling package core `of yielding rmaterial on .the spindle, 'the 'spindle having a recess covered by the core and lfacing laterally with respect'to the plane vof movability of the spindle, and

a claw arranged laterally of said plane and between one side of the spindle butt and the adjoining side of the cavity and having a claw-proper projecting toward, and holding the material of the core pressed into, said recess.

5. In combination, a. shuttle body having a filling-package cavity, a spindle having its butt fulcrumed in the cavity on an axis traversing the. same, a tubular filling package core of yielding material on the spindle, thespindl@ having a recess covered by the core and facing laterally with respect to the plane of movability of the spindle, and means .in the lshuttle body holding the material `of ytheJ core pressed into said recess.

4. In combination, a shuttle. body having a filling-package cavity, a spindle having its butt fulcrumed in the cavity on an aXis 'traversing the same, a tubular fillin package core of yielding material on the spindle, the spindle having yopposite lateral recesses covered by the core, and opposite mea-ns in the Vshuttle body holding the ymaterial of the core pressed into each recess.

5. In combination, a shuttle body having a filling-package cavity, a spindle having its butt `fulcrumed in the cavity on an axis traversing the same, a tubular filling :package core of yielding material on the spindle, vand a claw arranged at each side of the spindle butt and between the same and the adjoining side of the cavity, each claw, having a claw-proper projecting toward and arranged opposite the vclaw-proper of the other'claw and biting' into the material of the core.

6. In combination, a shuttle body having a :filling-package cavity, a spindle having its butt fulcrumed in the cavity on an axis traversing the same, a tubular lling package-core of yieldingV material on the spindle,

and a claw arranged at one -side of the spindle butt and :between the same -and vthe adjoining `side of the cavity and having a claw-proper projecting toward and biting into the material of the core and bearing againstI the side of the cavity. i In testimony whereof I aiiix my signature.
